LLM DNA: Tracing Model Evolution via Functional Representations
Researchers have developed a mathematical framework called LLM DNA that traces the evolutionary relationships between large language models through functional representations rather than documentation. The training-free method successfully identified previously unknown connections among 305 LLMs and constructed an evolutionary tree reflecting architectural shifts and temporal progression in model development.
